Method for controlling release and/or blocking of application functions in e.g. control apparatus of internal combustion engine of motor vehicle, involves storing diagnostic results in data format in matrix-like data structure

摘要

The method involves carrying out the release and/or blocking of application functions through a matrix-like data structure in which the results of a survey carried out by the control unit self-diagnosis functional-result-oriented stored. The diagnostic results are stored in a data format in the matrix-like data structure. The identifier for each function and the respective diagnostic result, and the release status and/or lock status of the respective function comprises indicative values. Independent claims are included for the following: (1) a computer program for controlling release and/or blockage of application functions in control unit during operation in motor vehicle; (2) a computer program product for controlling release and/or blockage of application functions in control unit during operation in motor vehicle; and (3) a control unit such as engine control apparatus of internal combustion engine of motor vehicle.
